The solution set of the inequality is:
w ∈ (-∞, -1] U [3, ∞)
How to solve the given inequality?
The graphed parabola is f(w), and we have the inequality:
f(w) ≤ 0.
So we need to identify the intervals such that the parabola is below the horizontal axis. By looking at the graph, we can see that the two intervals are:
Left side:
(-∞, -1]
Right side:
[3, ∞)
Where the brackets are used because points x = -1 and x = 3 are solutions.
Then the solution set of the inequality is:
w ∈ (-∞, -1] U [3, ∞)
